Hi
We are using DO kubernetes and trying to implement isolation of pod by network policy

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: "node-isolate"
spec:
  podSelector:
    matchLabels:
      app: myapp
      release: mydep
  policyTypes:
  - Ingress

myapp-6f5c8dbd6d-rql4t                  1/1       Running             0          1d        app=myapp,pod-template-hash=2917486828,release=mydep

But I can access pod from another pods with curl via service name and port,
Is DO use network stack that doesn’t support networkpolicies?
Like flannel?
